Lithium.
The charge if a fluorine atom were attract an extra electron from lithium the lithium atom would be positive. -APEX
Lithium has the lowest electronegativity, then carbon, bromine and fluorine has the highest electronegativity of any atom.
If an atom has all of it's outer orbitals filled it is non-reactive.
Let me start off by saying that the Lithium ion is not less reactive than the Lithium atom. In fact, Li+ is far more reactive than the Lithium atom, which is why it does not exist in its free state. Lithium ions tend to combine with anything it comes into contact with. However, it has a more stable electronic configuration than the Lithium atom, resembling that of a Noble gas(in the case of Li, it is Helium), which is why 1+ is the preferable oxidation state of Lithium.
Yes, a Bromine atom can bond to another similar Bromine atom, to make a Bromine molecule: Br2

Positively (apex)

No. argon is chemically unreactive due to the presence of completely filled orbitals.
Bromine is quite reactive because it is highly electronegative. Electronegativity is a chemical property that measures the ability for an atom to gain electrons from another atom. Thus, the more electronegative an atom is, the more reactive it is. Generally speaking, as you move up a group and across a period on the periodic table, the electronegativity increases. Fluorine has the greatest electronegativity, while francium has the lowest.
The anion has a negative electrical charge and is more chemically reactive than the atom.
the one that is completely filled
All the neutral atoms (except noble gases) are more reactive. To gain stability, they form ions; therefore, ions are less reactive.
Bromine atom= [Br]

This could not be done chemically. It would need a nuclear reactor. The likely product would be Lithium 5.
